These are notes taken from various decent SNG players.

Fold a lot early.

Patience and discipline.

Don't play too many pots. Less than 15%.

Necessity, ask yourself is this a move that I have to do. Do I have to make this play.

Most MTTers don't play well in SNGs because of doing too many moves.

Look for patterns in people.

Use while your playing resources like the hand history.

Play very conservative early in SNGs.

There's about 10 decisions per game that you have to make.

Just play it tight and safe early until the bubble and then use proper push/fold strat.
